Thank you for purchasing the Belkin Wireless G USB Network

Adapter (the Adapter). Now you can take advantage of this great

new technology and gain the freedom to network your home and

office computers wirelessly. This Adapter allows you to connect a

desktop or notebook computer to your network. The easy installation

and setup will have you networking wirelessly in minutes. Please

be sure to read through this User Manual completely, and pay

special attention to the section entitled “Placement of your Wireless

Networking Hardware for Optimal Performance” on page 2.

Benefits of a Home Network

Your Belkin Home Network will allow you to:

• Share one high-speed Internet connection with all the computers in

your home

• Share documents, music, video, and digital pictures

• Store, retrieve, and copy files from one computer to another

• Simultaneously play games online, check Internet email, and chat

Advantages of a Wireless Network

Here are some of the advantages of setting up a Belkin wireless network:

• Mobility – you no longer need a dedicated “computer

room”—you can work on a networked laptop or desktop

computer anywhere within your wireless range

• Easy installation – Belkin Easy Installation Wizards make

setup simple

• Flexibility – set up and access printers, computers, and other

networking devices from anywhere in your home

• Easy expansion – the wide range of Belkin networking products

lets you expand your network to include devices such as printers

and gaming consoles

Introduction

Placement of your Wireless Networking Hardware for Optimal

Performance

Your wireless connection will be stronger the closer your computer

is to your wireless router (or access point). Typical indoor operating

range for your wireless devices is between 100 and 200 feet. In the

same way, your wireless connection and performance will degrade

somewhat as the distance between your wireless router (or access

point) and connected devices increases. This may or may not be

noticeable to you. As you move farther from your wireless router (or

access point), connection speed may decrease. Factors that can

weaken signals simply by getting in the way of your network’s radio

waves are metal appliances or obstructions, and walls.

If you have concerns about your network’s performance that might be

related to range or obstruction factors, try moving the computer to a

position between five and 10 feet from the wireless router (or access

point) in order to see if distance is the problem. If difficulties persist

even at close range, please contact Belkin Technical Support.

Note: While some of the items listed below can affect network

performance, they will not prohibit your wireless network from

functioning; if you are concerned that your network is not operating

at its maximum effectiveness, this checklist may help.

1. Placement of your Wireless Router or (Access Point)

Place your wireless router (or access point), the central connection

point of your network, as close as possible to the center of your

wireless network devices.

To achieve the best wireless network coverage for your “wireless

clients,” (i.e. computers enabled by Belkin Wireless Notebook

Network Cards, Wireless Desktop Network Cards, and Wireless USB

Adapters):

• Ensure that your wireless router’s (or access point’s) antennas

are parallel to each other, and are positioned vertically (toward

the ceiling). If your wireless router (or access point) itself is

positioned vertically, point the antennas as much as possible in

an upward direction.

• In multistory homes, place the wireless router (or access point) on a

floor that is as close to the center of the home as possible. This may

mean placing the wireless router (or access point) on an upper floor.

• Try not to place the wireless router (or access point) near a

cordless 2.4GHz phone.

2. Avoid Obstacles and Interference

Avoid placing your wireless router (or access point) near devices that

may emit radio “noise”, such as microwave ovens. Other objects that

can inhibit wireless communication can include:

• Refrigerators

• Washers and/or dryers

• Metal cabinets

• Large aquariums

• Metallic-based, UV-tinted windows

If your wireless signal seems weak in some spots, make sure that

objects such as these are not blocking the signal’s path between

your computers and wireless router (or access point).

3. Cordless Phone Placement

If the performance of your wireless network is impaired after

attending to the above issues, and you have a cordless phone:

• Try moving cordless phones away from the wireless router

(or access point) and your wireless-enabled computers.

• Unplug and remove the battery from any cordless phone

that operates on the 2.4GHz band (check the manufacturer’s

information). If this fixes the problem, the phone may

be interfering.

• If your phone supports channel selection, change the

channel on the phone to the farthest channel from your

wireless network as possible. For example, change the

phone to channel 1 and move your wireless router (or

access point) to channel 11. (Your channel selection will

vary depending on your region.) See your phone’s user

manual for detailed instructions.

• If necessary, consider switching to a 900MHz or 5GHz

cordless phone.

54

4. Choose the “Quietest” Channel for your Wireless Network

In locations where homes or offices are close together, such as apartment

buildings or office complexes, there may be wireless networks nearby

that can conflict with yours. Use the Site Survey capabilities of your

Wireless Networking Utility to locate any other wireless networks,

and move your wireless router (or access point) and computers to a

channel as far away from other networks as possible.

Experiment with more than one of the available channels in order to

find the clearest connection and avoid interference from neighboring

cordless phones or other wireless devices.

For more Belkin wireless networking products, use the detailed site

survey and wireless channel information included in your User Manual.

5. Secure Connections, VPNs, and AOL

Secure connections typically require a user name and password, and

are used where security is important. Secure connections include:

• Virtual Private Network (VPN) connections, often used to connect

remotely to an office network

• The “Bring Your Own Access” program from America Online

(AOL), which lets you use AOL through broadband provided by

another cable or DSL service

• Most online banking websites

• Many commercial websites that require a user name and

password to access your account

Secure connections can be interrupted by a computer’s power

management setting, which causes it to “go to sleep.” The simplest

solution to avoid this is to simply reconnect by re-running the VPN or

AOL software, or by re-logging into the secure website.

A second alternative is to change your computer’s power management

settings so it does not go to sleep; however, this may not be appropriate

for portable computers. To change your power management setting in

Windows, see the “Power Options” item in the Control Panel.

If you continue to have difficulty with Secure Connections, VPNs, and

AOL, please review steps 1-4 in the previous pages to be sure you

have addressed these issues.

These guidelines should allow you to cover the maximum possible area

with your wireless router. Should you need to cover an even wider

area, we suggest the Belkin Wireless Range Extender/Access Point.

Wired Equivalent Privacy (WEP) is a less secure, but more

widely adopted wireless security protocol. Depending on the security

level (64- or 128-bit), the user will be asked to input a 10- or 26-

character hex key. A hex key is a combination of letters, a–f, and

numbers, 0–9.

Wireless Protected Access (WPA) is the new standard in

the wireless security. However, not all wireless cards and adapters

support this technology. Please check your wireless adapter’s user

manual to check if it supports WPA. Instead of a hex key, WPA uses

only passphrases, which are much easier to remember.

The following section, intended for the home, home office, and small

office user, presents a few different ways to maximize the security of

your wireless network.
